It is an unassuming, timeless marvel of mysterious origins and significant usefulness. It remains an artifact unto itself, providing illumination for those who need it in their lives, and moving on, ever ready to serve and light the darkness for the next master.
Basq doesn't exist. He occupies a point in space--a single X,Y,Z point in the Cartesian plane, but he's not made of anything. People looking at him see whatever they want to see. Or what he wants you to see. Usually a mix. Just the same, he cannot be hurt swords or arrows. Only things that deal damage to an area (fireballs, gases) can damage him. Or weapons that can cut through an infinitely small point.
